Flexible Configuration: The Powersoft DUECANALI 6404 DSP amplifier supports a variety of configurations to accommodate diverse audio applications. It easily handles low-impedance loads starting from 2Ω while also supporting 70V and 100V distributed lines. This flexibility allows users to implement mixed impedance output loads, making it suitable for various settings, from live events to fixed installations.

Integrated DSP Functionality: At the heart of the DUECANALI 6404 DSP is a fully integrated state-of-the-art digital signal processor (DSP). This advanced DSP provides extensive system management capabilities, including sound shaping and limiter functions. With compliance to IEC 60849 standards, it ensures reliable performance for emergency sound systems. The ArmoníaPlus software further enhances system control, enabling users to optimize audio quality and manage complex setups with ease.

Advanced Power Supply: The amplifier features Powersoft’s renowned universal switch-mode power supply, which is tolerant of input voltages up to 400VAC. This power supply includes Power Factor Correction (PFC) to enhance efficiency and reduce operational costs. Additionally, the built-in Low Inrush Limiting technology minimizes AC inrush current, eliminating the need for expensive power sequencers, which simplifies installation.

Comprehensive Protection Mechanisms: To ensure reliability, the DUECANALI 6404 DSP incorporates a fully protected circuit design. It includes AC protection that shuts down the power supply when voltage fluctuates outside the operating range. The clip limiter prevents distorted waveforms from reaching loudspeakers while maintaining full peak power output. Other protective features include DC protection, VHF protection, short circuit protection, and thermal protection, ensuring safe operation even under demanding conditions.

Lightweight and Compact Design: Designed for convenience, the DUECANALI 6404 DSP is compact, fitting into a single rack unit and weighing only 7 kg (15.4 lbs). This lightweight design facilitates easy transportation and installation, making it an ideal choice for both touring and permanent setups. Its standard Phoenix connectors for analog audio outputs, alarms, and GPIO simplify connectivity and enhance usability.

Monitoring and Control Options: The DUECANALI 6404 DSP offers multiple monitoring and control options. Users can control and diagnose the system via the ArmoníaPlus software or a dedicated WebApp. Hardware control options include attenuation adjustments, high-pass filter settings, and output selection for Lo-Z and Hi-Z configurations. These features allow for seamless adjustments to meet specific audio requirements.
